A little confused

[ForestWolf]

Hi, im a little confused about lighting/UVB.
A 40 W - 50 W, on 24 hours a day, is good?
then, For uvb.
Do they need UVB?
Im a little confused about that one, Becuase -
Wont it be like a turn off at night thing, so they know its night?
I also read some were, that, in there food theres some D3 is what ever its called, and, in the UVB light, theres D3, Would they get to much D3?

You will need to use a temp gauge and a humidity gauge to find out if you even need a light on. It is different in each house, in each kind of enclosure.

You can offer UVB, but the Crested Gecko Diet is formulated in such a way that many feel it is unnecessary for a healthy crested gecko. Because these geckos do a fair job of hiding when any lights are on (hidden under leaves, hides etc.) their benefit from UVB may be a lot less than a regular basking lizard. D3 is used in the processing of calcium in the body, helped along with UVB light.

Just remember, you do need a dark period and a light period, so white lights like UVB need to be shut off at night.

On colder nights, some of my geckos stay active with a red light on and seem to gravitate to the warmer side of the tank, but if your area is already warm enough it should be unnecessary.

The general consensus is that cresties don't need UV light. The reasoning is since they are nocturnal and hide during the day they get little to no UV rays in the wild. you do need to give a light cycle but a normal house light bulb will do. the D3 in their food is all they need, as long as you are using a complete diet such as Repashy super food. as far as i know you would have to feed an exceedingly large amount of D3 to hurt the gecko, they typically just pass any extra nutrients.

There actually isn't D3 in UV rays, but the body of many animals produces D3 when exposed to UV rays. This aids in the absorption of calcium. So this is why it is very important reptiles get as much as they need.
